What's your fandom and why?

I really got in to Dr. Who and before that Star Trek because I think there’s an overall optimism about the future. There’s lots of neat new tings to do and explore in these worlds. That’s probably why I also like the Final Fantasy RPG games as well. I’d love to hear about your favorite Geek moment! Anyway, feel free to brag about your favorites and why you love them! This may seem lame… My all time favorite fantasy character is the Chocobo. :)
